Histopathologic examination showed basal hyperpigmentation without an increased number of melanocytes. Polymerase chain reaction amplification of complementary DNA SPRED1 gene and mutational analysis by direct sequencing were performed. A c.781delT germline-dominant loss-of-function mutation in exon 8 of the SPRED1 gene (15q13.2) was identified. Genetic counseling was given to the patient.
Yearly follow-up controls (cutaneous, ophthalmological, and neurological examination) were recommended. During the past 4 years, no additional cutaneous or extracutaneous features have been noted. No cutaneous findings of neurofibromatosis type 1 were identified among the patient's relatives.
